Changing font of a tree control item

Pretty basic question but I just started learning a few days ago and I don't have a book or any source of help besides the .hlp files vc++ 5.0 came with, so be nice :) Ok, I created and added an item my tree control, but not how can I use SetItem() to change the font of the item to bold? For example, I have this:

HTREEITEM a = m_tree.InsertItem(title, TVI_ROOT, TVI_LAST);

with m_tree and titled taken care of. Now, if I want to turn that item bold I do something along the lines of this (help me - fill in the ?s and make any needed corrections please =), oh and btw, I dont have images on the tree):
